After the idea of Formula E was presented, many thought about another short-lived racing series like many others before.
For example A1GP. I liked the idea of a nations cup, and we had strong drivers and some exotic ones. A nice field I think.
Or GP Masters - with former F1 drivers driving Formula cars again.
Or Superleague Formula - nice cars, but the idea to combine football and Racing together was a bad idea.
Any other short-lived racing series, perhaps with good ideas behind?
